15 Plagiarism Detection Tools for Bloggers and Writers

There’s no difference between copyright law in cyberspace and print media; the same law applies both online and offline. You can check to see if your content has been stolen, and file DMCA take-down notices with the appropriate web host when it has been.

Copyrightable works include but are not limited to literary works such as articles, blog posts,  stories, journals, or computer programs, pictures and graphics, as well as audio and video recordings (recipes are excluded).

A couple of hours after I publish a new article I use search engines, meta search engines and/or online plagiarism checkers to search for specific quotes from my article. After I get the first results from one search engine, usually Google,  depending on what’s revealed I can continue to search and catch the RSS Feed scrapers who have stolen my content. Thereafter I periodically run random checks for plagiarism of my older posts and specific checks  for plagiarism of my most popular posts.

Here’s an example (Google limits queries to 32 words.):

It includes the search engines, meta search crawlers, grammar checkers and plagiarism tools that I’m most likely to use to detect unauthorized duplication of my content on the internet.

  1. Timethief,
    I was wondering what your thoughts are on the “Press This” function of WordPress. I have a scheduled post where I used this function but am hesitant in publishing it.

    Credit is given to the originating website automatically in the blog title and excerpt inside the post.
    Your thought would be greatly appreciated!
    Greg

  2. Helpful info, timethief! Thank you. I’d like to share the link to this post with a writers group of which I am a member. I’m sure you would not mind my doing that, but after reading your post I am feeling uber-careful!

  3. Thanks again for another comprehensive post – you mention usually using Google a couple hours after posting. I am a bit confused. Could you explain in brief the steps you take to complete the search. I hope this question makes sense. Thanks.

    1. You simply go to Google search and enter a quote from your freshly published posts and search. I added an example to my post above so you know how to do this.

  4. Very useful tips and thank you. I never use any of them of have the attitude of ‘who is going to steal my stuff and why’? It’s hard enough to get visits and comments in the first place. However, because you are giving useful and helpful tips it is another ball game. Here’s wishing you all the best and blast all scammers.

  5. Thank you for this. A friend of mine had a pattern and almost all of her post copied and passed off as someone else’s. I didn’t quite get it at the time but I do now. I have some resources to pass on now with due credit given of course. :) Also as soon as I get time (I am in the middle of trading my old laptop up which is great but yet another learning curve to do so) I will use Copyscape on my blog. I honestly wouldn’t have thought content thieves would bother with amigurumi craft sites but apparently they do! and have!

    1. Hi there,
      I’m glad I was able to provide some basic education of the tools that can be used. I think there are a lot of new bloggers who may not know about determining if their content has been stolen and filing DMCA notices to get it removed from splogs so please pass it on.

  6. For images I’ve used google image search, but dogpile search sounds useful too. I see the DMCA takedown is a paid service, which I can understand. This should be a featured post.

        1. What are you referring to?

          No matter where a splog is being we hosted you file a DMCA take-down notice with their web host – free of any charges. See the support docs at http://support.wordpress.com
          Prevent Content Theft
          Content Theft – What to Do
          DMCA

          Under section 1201 of the Digital Millennium Copyright Act (DMCA), the circumvention of these access mechanisms is illegal, with only a few narrow statutory exemptions. The DMCA also prohibits the distribution of programs that can be used to circumvent both copy control and access control technologies. Under DMCA, we discuss the ISP safe harbor and its conditions (notice and takedown), and the anticircumvention provisions of section 1201. http://chillingeffects.org/anticircumvention/

          1. I did not provide that link above because no one has to be a a member of that site to file a DMCA notice. That site is for those who want to pay others to do it all or at least do part of it for them. Everyone can do their own research to determine who hosts the site with their plagariarzed and/or stolen content on it and then they can file their own DMCA notice with the web host.

            Drafting and sending a DMCA Notification is usuallyeasy as most ISPs even provide their users with a form (or at least a detailed walk-through) on how to submit a DMCA complaint. I linked to the DMCA support doc for Automattic which owns WordPress.com as they are who to contact if your content is stolen by a blogger hosted by WordPress.com. However, every site has their own and none of us have to spend a single cent to file a DMCA takedown notice.

          2. Yay! You understood me. I think bookmarking it is a good thing to do because it seems inevitable that some creepy crawler will steal your content at some point in time.

  7. These sound like fabulous tools. I was not aware of any but Copyscape. I appreciate this information, as I had actually not thought to check if folks were stealing my stuff.

    1. Hi Kathy,
      The digital content market has grown rapidly and will continue to grow. Advertizes naturally take advantage of that. Content theft grows exponentially as well because it doesn’t take much to hire a web host and set up a slog sucking in content from RSS feeds, while also benefiting from clicks on ads you place on the site. The gains you get from pimping the blog are minimal in most cases and those who play the game are limited on many levels.

    1. Hi Olivia,
      The sites I posted links to are very easy to use and produce quick results. It’s good to know you tried and liked using the Dustball plagiarism detector. Best wishes for trouble-free blogging.

    1. You file a DMCA take-down notice with their web host. See the support docs at http://support.wordpress.com

  8. Thanks for the list and reviews. I’ve seen the Copyscape logo on blogs and wondered about it. It has been frustrating to locate your work pirated to other place – wasn’t sure how much time was involved with protesting/DMCA. Appreciate what you’ve gathered here

    1. You’re welcome and if you have not acted to do all you can to prevent content theft then I suggest you do. Granted copyright notices and copyscape notices may not deter the most determined thieves but they will deter some.

  9. [ Smiles ] You really did your homework with this one. Thanks for sharing the vast information!

    1. Thank you. I summarized just some of the tools I use for blogging. For my contracted work, which I cannot and will not discuss in my blog, I use a different computer and I have paid services. I recommend all those who intend to make part of their income from writing use paid tools which can be easily found by searching using Google. Tracking blogs that violate rules on duplicate content is a complicated process. In fact some sploggers who excel in SEO succeed in manipulating search engines into ranking them better than the real owners of the copied content until they are caught out doing it.
